Well, the knocking down of the pixel count/area to speed up
capture and frame rates (8ps) was a suggestion made ages ago
when people wondered why they had a 4 megapixel pro camera at
all. What exactly is the "H" for nowadays and why, if the sensor
is the expensive part of camera does the H still cost what it does??
And as a side issue, why must most cameras "bin" pixels when
resolution or "quality" is reduced? They combine pixels to
cut the resolution which results in larger pixels. Since resolution
is being reduced, why not simply use the pixels in the centre of the
sensor? This would achieve the same objective as "binning" and would
allow lenses to "become" different focal lengths. They would increase
in focal length. So, (as a rough example) you're 8 megapixel camera
with it's 50-200mm lens could become at the push of a button a 4
megapixel camera with a 100-400mm lens, without changing lenses.
What Nikon has done by allowing this reduction in true pixel count is
smart, it's bought them speed and focal length flexibility.
